But I know what you mean. I think those icing colors operate under the same principle as oil paints; different colors are made of different things and the blue is ALWAYS nasty. And the red isn't much better.

Picky eater here also, like most green veggies, liver, not much on fish, chinese . Also much eaiser to list what I will eat not what I wouldn't.
My one main rule of thumb if it doesn't look good I am not eating it.

The following I will eat with specifications:
American cheese (only as grilled cheese or on an egg and cheese sandwich)
Sausage (only boiled)
Pasta (VERY rarely, like, I have to be very hungry and there must be ricotta and parmesian cheese)
Mayonnaise (ONLY mixed in tuna salad or chicken salad)
